I don't see any tool using PQping except pg_ctl.  Perhaps we should
modify "pg_ctl status" to use PQping.  Right now is only checks the file, and checks to see that the pid is a running
postmaster.  What it currently doesn't do is to check if the server is
accepting connections with PQping(), like we do for "pg_ctl -w start".
